iio: Don't silently expect attribute types

The iio_triggered_buffer_setup_ext() and the
devm_iio_kfifo_buffer_setup_ext() were changed by
commit 15097c7a1adc ("iio: buffer: wrap all buffer attributes into iio_dev_attr")
to silently expect that all attributes given in buffer_attrs array are
device-attributes. This expectation was not forced by the API - and some
drivers did register attributes created by IIO_CONST_ATTR().

When using IIO_CONST_ATTRs the added attribute "wrapping" does not copy
the pointer to stored string constant and when the sysfs file is read the
kernel will access to invalid location.

Change the function signatures to expect an array of iio_dev_attrs to
avoid similar errors in the future.

KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features
include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ,
tap/motion detection, wake-up & back-to-sleep events, four acceleration
ranges (2, 4, 8 and 16g), and probably some other cool features.

Add support for the basic accelerometer features such as getting the
acceleration data via IIO. (raw reads, triggered buffer [data-ready] or
using the WMI IRQ).

Important things to be added include the double-tap, motion
detection and wake-up as well as the runtime power management.

iio: health: max30102: do not use internal iio_dev lock

The pattern used in this device does not quite fit in the
iio_device_claim_direct_mode() typical usage. In this case, we want to
know if we are in buffered mode or not to know if the device is powered
(buffer mode) or not. And depending on that max30102_get_temp() will
power on the device if needed. Hence, in order to keep the same
functionality, we try to:

1. Claim Buffered mode;
2: If 1) succeeds call max30102_get_temp() without powering on the
   device;
3: Release Buffered mode;
4: If 1) fails, Claim Direct mode;
5: If 4) succeeds call max30102_get_temp() with powering on the device;
6: Release Direct mode;
7: If 4) fails, goto to 1) and try again.

This dance between buffered and direct mode is not particularly pretty
(as well as the loop introduced by the goto statement) but it does allow
us to get rid of the mlock usage while keeping the same behavior.

Note that we are shadowing the error code returned by
